Hand-guided, self-propelled marking machine RP100-1H

The Hofmann RP100-1H is a hand-guided self-propelled thermoplastic screed marking machine for medium-scale operations with frequent direction changes, powered by a single-cylinder Honda petrol engine with 200 cm³ displacement, air-cooled, delivering 4.0 kW at 3,500 rpm. The hydrostatically driven rear wheels are propelled via a stepless variable hydraulic drive, with a differential drive ensuring equal, smooth power distribution between both rear wheels in all operating conditions. The machine dimensions are 1,800 mm (L) x 1,200 mm (W) x 1,200 mm (H) depending on equipment configuration, with an operating weight of 410 to 450 kg. The thermoplastic material container holds up to 115 liters. The glass bead container holds up to 20 liters. The built-in two-cylinder compressor delivers up to 320 liters per minute of air. The screed shoe mounting point is located on both left and right sides of the machine. Indirect thermal oil heating with automatic temperature control maintains the material at consistent application temperature. The machine is CE compliant for self-propelled travel. Marking widths range from 10 to 50 cm depending on equipment selection. Optional equipment includes double-line screed shoe attachment and ELC4 or ELC1plus line-spacing electronics.

The hydrostatic variable drive transmits the Honda engine’s output to the rear wheels through a continuously variable hydraulic circuit — the operator controls forward speed steplessly via the handle-mounted drive control without gears or clutch. The differential drive distributes torque between the two rear wheels according to ground contact load, preventing wheel slip on uneven surfaces and maintaining consistent straight-line tracking during long marking runs. The low-noise petrol-hydraulic drive combination makes the RP100-1H particularly suited to urban and residential area operations where noise levels must be minimized during marking work. The indirect thermal oil heating system protects the thermoplastic material from direct heat contact and maintains screed application temperature during wind exposure and work interruptions without operator intervention.

The Hofmann RP100-1H is deployed by road marking contractors for medium-scale urban thermoplastic marking operations — including car park layouts with frequent screed repositioning, urban road markings with many start/stop cycles, intersection markings, pedestrian crossing work, and supplementary marking operations alongside self-propelled machine programs on the H-series platform. It is also documented as a companion machine to the HG-series self-propelled machines with HK1000-1 cooker combinations.

Leader Infra supplies this hydrostatic self-propelled thermoplastic screed machine for road marking contractors — delivering stepless variable drive, differential rear wheel traction, indirect thermal oil heating with automatic temperature control, and left/right screed shoe mounting across 10 to 50 cm line widths in a 410 to 450 kg operator-guided machine.

FAQ — What is the operational advantage of the hydrostatically variable drive on the RP100-1H over a fixed-speed or gear-driven wheel drive? The stepless hydrostatically variable drive allows the operator to precisely match the machine’s forward speed to the marking conditions at any instant — accelerating between marking sections and decelerating smoothly into each new start point without mechanical gear changes or clutch engagement. On frequent-direction-change operations like car park layouts, this eliminates the disruptive stops and gear-change delays of mechanical drive systems, allowing faster repositioning and more consistent start/stop marking quality across the full job.
